Inventory and Device Management

The Inventory page helps you manage, monitor, and organize Remote PHY and CCAP Core inventory. You can quickly view inventory details such as Device Name, Device IP address, MAC address, Product Type, RPD Software version, Tags, and so on. CCAP can be both managed and unmanaged; Non-Cisco RPDs, if supported by Cisco cBR-8, can also be added in Smart PHY.

Cisco Smart PHY supports 50,000 RPDs on a 3-node cluster. Because the number of RPDs provisioned by the Cisco Smart PHY scales into such huge numbers, we recommend that the Operators work on Cisco Smart PHY programmatically using its REST API.

The Following fields are available in the Inventory page.

Credential Profiles

Credential profiles are collections of device credentials to Telnet or SSH to cBR8 devices. When you add or import devices, you specify the credential profile the devices you want to use. You can apply same or different credential profiles across devices.

For information regarding Credential Management, see Credential Profiles.


Note

We recommended that you add RPDs through Cisco Smart PHY RPD Association page and not through the Inventory page. The RPD Association page creates an inventory record automatically. For more information see, Creating an RPD Association.

Fetching SSH Keys from Cisco cBR-8

Use this procedure to fetch SSH keys.

  1. Click the main menu at the top-left of the home page, and select Smart PHY > Inventory.

    The Remote PHY Devices & CCAP Cores page displays.

  2. Select the check boxes of one or more cBR-8 routers as required.

  3. Select Fetch SSH Keys in the Managed CCAP Actions drop-down list.

    • During the key fetch, the cBR-8 router's status appears as SSHKEYFETCH_PROGRESS.

    • The following pop-up message appears when the key fetch is successful:

       Successfully fetched SSH keys from the selected cBR-8(s)

Fetch SSH Keys Using REST API

Use the following asynchronous API to Fetch the SSH keys: 
rpd-service-manager/rpdorch/v1/core-topology/fetch-ssh-key
You can fetch the SSH keys for all Cisco cBR-8 routers in the Cisco Smart PHY application, by setting the allCore parameter to true in the request message of rpd-service-manager/rpdorch/v1/core-topology/fetch-ssh-key.
{
"allCore": true,
"ipAddressList": [
"192.0.2.1", "192.0.2.100"
]
}
Check the status of fetching the SSH keys using the following API:
inventory-manager/inventory/v1/device/query-device-list

Limitations for Fetching SSH Keys

Smart PHY prohibits SSH key fetches for a cBR-8 router when:

  • An SSH Key Fetch operation is already underway for a selected cBR-8 router.

  • The status of the selected cBR-8 router is Unknown.


Note

  1. Cisco Smart PHY 3.1.4 and later, supports fetching SSH keys from both online and offline Cisco cBR-8 routers.

  2. Cisco Smart PHY 3.1.3 and earlier, supports fetching SSH keys only from online Cisco cBR-8 routers.

Disabling Southbound Communication to Cisco cBR-8 Router

During normal operation, Smart PHY periodically checks the managed cBR-8 routers for liveliness and configuration sync. You can disable those checks and GCP redirects to select cBR-8 routers by placing them in Maintenance Mode. Disabling the southbound communications allows the selected cBR-8 routers to undergo maintenance without interference from Smart PHY.

Setting Maintenance Mode

Use this procedure to set a cBR-8 router to maintenance mode:

  1. Click the main menu at the top-left of the home page, and select Smart PHY > Inventory.

    The Remote PHY Devices & CCAP Cores page displays.

  2. Check the check box of cBR-8 routers as required.

  3. From the Managed CCAP Actions drop-down list, click Enable Maintenance Mode.

When a cBR-8 router is in the maintenance mode:

  • The status of the router in the UI is Maintenance Mode.

  • You are blocked from making any configuration changes through Smart PHY's UI or its V2 API.

  • RPDs associated with the cBR-8 router are not GCP redirected.


Note

Smart PHY does not block Version 1 (V1) of its RPD-pairing REST API when a cBR-8 router is in the maintenance mode. Smart PHY only blocks V2 API calls.

Resuming Normal Operation

Use this procedure to resume normal operation on a cBR-8 router:

  1. Click the main menu at the top-left of the home page, and select Smart PHY > Inventory.

    The Remote PHY Devices & CCAP Cores page displays.

  2. Select the check boxes of one or more cBR-8 routers that are in the maintenance mode.

  3. From the Managed CCAP Actions drop-down list, click Resume Maintenance Mode..

  4. Review the Warning message, and then click Resume Normal Operation.

The consistency checks that Smart PHY performs when returning a cBR-8 router to normal operation often take several minutes to complete. While the checks are running the cBR-8 router's state displays as NORMALOPS_PROGRESS. Once the check is complete, the state of the router updates to reflect the results: Online or Offline

Restricted Cisco Smart PHY Operations

When Cisco Smart PHY detects a Cisco cBR-8 router as offline, Cisco Smart PHY does not allow you to do the following:

  • Provision RPDs

  • Fetch Details

  • Import

However, you can edit, export, or delete the devices from the Inventory page.
